Actually, I've upgraded ccache to _2 and it doesn't say anymore what to put=
in=20
make.conf. Is it still :
=2Eif ${.CURDIR:M/usr/src*} || ${.CURDIR:M/usr/obj*}
CC=3Dcc
CXX=3Dc++
=2Eelse
=2Eif defined(NOCCACHE)
CC=3D/usr/bin/cc
CXX=3D/usr/bin/c++
=2Eelse
CC=3Dcc
CXX=3Dc++
=2Eendif
=2Eendif
or is it :
#.if !defined(NOCCACHE)
#.if ${.CURDIR:M/usr/src*}
#CC=3D/usr/local/libexec/ccache/cc
#CXX=3D/usr/local/libexec/ccache/c++
#.else
#CC=3Dcc
#CXX=3Dc++
#.endif
#.else
#CC=3D/usr/bin/cc
#CXX=3D/usr/bin/c++
#.endif
and do I still have to setenv CCACHE_NOHASH_SIZE_MTIME yes for a=20
buildworld/kernel?
Thanks,
Nicolas.
